Growing urbanization, shifting water uses, and a focus on ecosystem health in the Deschutes River Basin in Central Oregon led to experimentation with new voluntary market-based approaches to water management in the last ...

The Columbia River Channel Improvement Project (CRCIP) was constructed along 166.6 km (103.5 miles) of Columbia River (from River Mile 3 to 106.5), which was from Interstate 5 Bridge (between Portland and Vancouver) to t ...

Before 2002, almost all of the approximately 40,000 acres of land in the Wood
River Valley, Oregon were used for intensive, flood-irrigated summer cattle grazing,
as it had been for over 100 years. Conservation activit ...

Tribal water rights and instream flows for species listed under the Endangered Species Act (ESA) have been a source of tensions in the western United States, particularly when tribes have undetermined water rights to sup ...

Water governance has been identified as a crucial component to improving conditions and balancing supply and demand of water resources in the water-scarce Middle East North Africa (MENA) region. Finding a method for, and ...

In the Middle Rio Grande region of New Mexico, challenges such as droughts, growing
urban demand for water, and newly listed endangered species have forced people to
change the way that they manage water. New challenge ...

The Wood River Basin lies upstream of Upper Klamath Lake, the main reservoir of the USBR Klamath Irrigation Project that provides irrigation water to 210,000 acres of downstream land. Water allocation became a contentio ...

Re-establishing connectivity is a primary restoration activity for enhancing the
recovery of migratory fishes, but actions are often limited by lack of funds and
understanding of the benefits of individual projects. Th ...

Irrigated agriculture accounts for 90 percent of consumptive use of freshwater in the
western US and is considered the largest contributor to nonpoint source water
pollution. The diffuse nature of most water quality an ...

This dissertation integrates a process-based hydrological investigation with an
ongoing paired-catchment study to better understand how forest harvest impacts
catchment function at multiple scales. We do this by addres ...

This study evaluates the use and efficacy of biochar for treatment of source and nonpoint source pollutants in storm water. Biochar is the solid byproduct of incomplete combustion of biomass under low-oxygen and elevated ...

The Oregon Coast's small water systems, like the vast number of small water systems across the U.S., are greatly vulnerable. Failing infrastructure, limited financial capital, and inadequate staff combined with future ch ...

Vertisols and other vertic-intergrade soils are found all over the globe, including many agricultural and urban areas. These soils are characterized by their cyclical shrinking and swelling behaviors, where bulk density ...

Emerging river policy has launched small dam removal as a viable option to meet the ecological and social demands for river restoration. As small dam removals gain precedence as a policy tool in river restoration project ...

A relatively stable, persistent and historical problem with elevated NO₃⁻ concentrations in rural drinking wells in the southern Willamette Valley, Oregon is evident. What is the origin of NO₃⁻ in rural drinking water we ...

Throughout many of the world’s mountain ranges snowpack accumulates during the winter and into the spring, providing a natural reservoir for water. As this reservoir melts, it fills streams and recharges groundwater for ...

Collaboration between scientists and decision makers is a critical element in
mobilizing science into action. Likewise, the United Nations defines collaboration
between scientists and policymakers as a requisite compon ...

Evapotranspiration (ET) is an important component of the hydrologic cycle that transfers large quantities of water vapor away from Earth's surface into the atmosphere. In addition to having agricultural water management ...

Bar-pool morphology in rivers can provide vital habitat to aquatic species, notably salmonids, which require gravel riffles to bury eggs and pools for hydraulic and cold-water refuge. In some cases, the erosion and subse ...

Recent developments in Distributed Temperature Sensing (DTS) have allowed
new insight into the surface-to-ground water interaction. The continuous temperature
measurement by the DTS allows for cool water inflows to be ...
